Finally, it was admiral Marcus who placed the Enterprise in such a desperate situation with the warp drive not functioning, it was admiral Marcus who opened fire on the Enterprise crippling this ship. It was NOT Khan who inflicted such damage on the Enterprise, so why didn't Spock scream 'Marcusssss!!!' or something of that sort?

In fact I'm surprised by how many people have overlooked this!

It was Khan who launched the final salvo against the Enterprise after beaming Kirk Scotty and Carol back aboard. It was this attack that sent it falling into the atmosphere. The Enterprise was in pretty good shape until then.
